Find the angle of inclination of:
3x + 6y= 18
- The formula we will use for this problem is m=tan(alpha)
- Alpha= angle of inclination
- In this problem, m= slope. m= -A/B so m= -3/6= -1/2
- Now we know that tan(alpha)= -1/2
- YOu need to solve for alpha and than you should get alpha= tan-(-1/2)
- tan-(-1/2)=26.565
- Now you need to find which quadrants tan is negative in. It is negative in quadrants 2 and 4.
- You take 26.565 and make it negative than add 180 to move to Q2 and you get 153.435
- Than you make 26.565 negative and add 360 to move to Q4 and you get 333.435.
- 153.435 degrees abd 333.435 degrees are your two answers.
I hope you enjoyed this weeks edition of the "Cory Teaches You How to do Something Show". I would like to give a special thanks to Peter Katerjian for calling me and asking me to send him a picture of my math notes so he could do his blog. Without him calling me and asking me to do that, I never would have remembered to do this magnificent, awesome, superb, incredible, unbelieveable, extraordinary(and a bunch of other adjectives you can think of) blog. Well there you have it folks, thats all for tonights show. Join me next weekend so i can teach you how to do something else. Gee Willickers i cant wait. Goodnight everybody.
